Ease of use. Reduction of many third party and add-on software such as DB schema and management tools, security, roles, permissions, aesthetics and theme, API connectors, and so much more. The most important area is the use Java without having to get stuck with boilerplate, and verbose code. Wavemaker reduces code writing by more than 80%.
Deployment is across the board to web, and mobile (iOS, Android). No other platform gives this much. The role of Java is very important as it has widely available libraries, and has matured to become very stable. Other languages have not matured or adopted to the level of Java.
For us, the decision was to move away from module and depencies often associated with WordPress, Drupal and other popular platforms. In addition, .NET and ,many others do not have an IDE that reduces code writing. In order to save time and work within budget we needed a RAD tool to make the deadline. This was only possible with Wavemaker.
The vast number of Java libraries made it seamless to integrate Wavemaker to AWS, CloudFront for our video sharing project. Wavemaker is a vast tool beyond the scope of this review. Try it yourself and see how much time can be saved.
